Let's divide 254345 by 79
The aim is to understand the frequency of 79 in 254345.

Advancing to step 1:
When dividing 2 by 79, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 79

Step 2:
79 can be fit into 25 0 times, resulting in a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Bring next digit (4) of the dividend behind the 25 and repeat the process: 254 / 79

Advancing to step 3:
254 divided by 79 is 3 with a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 237 from 254, we get 17.
Append the next digit (3) from the dividend to 17 and continue with: 173 / 79

On to step 4:
When dividing 173 by 79, we get 2 with a remainder of 15.
The next digit of our result is 2. 
Result so far: 32.0
If we take 158 away from 173, we end up with 15.
Include the next digit (4) from the dividend after 15, then repeat: 154 / 79

Let's proceed to step 5:
If we divide 154 by 79, we get 1 and a remainder of 75.
Put 1 as the next digit of the answer. 
Result so far: 321.0
If we subtract 79 from 154, we get 75.
Take the next digit (5) from the dividend and append it to 75, then repeat: 755 / 79

On to step 6:
79 goes into 755 9 times with a remainder of 44.
Put 9 as the next digit of the answer. 
Result so far: 3219.0
Subtracting 711 from 755 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 7:
79 goes into 440 5 times with a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 3219.5
If we take 395 away from 440, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 8:
450 divided by 79 is 5 with a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 3219.55
Subtract 395 from 450 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

After the division, we end up with 3219.55 and a remainder of 0.055.
